Hi, I have a Canon 350D camera Made in Japan. It is a very good camera. I am currently saving up to buy a Canon 600D and also need a 300 / 400 lens beside the two I already have (18-55 and 55-250 Canon). Please let me know by voting which one should I go for. I am specially interested in wildlife photography. Thanks

Larger insects a favorite? Canon 300mm f/4L IS, it has near macro capacity of 0.33x magnification, just the thing for dragonflies and butterflies.Mostly birds, especially birds in flight? Canon 400mm f/5.6L (no IS, but you don't need it, your shutter speed is high). Lightweight, snappy autofocus, tack sharp wide open. This is my long telephoto lens.Mammals and birds? Canon 100-400mm f/4-5.6 L IS, gives you the extra reach for small birds but allows use for average and large mammalsMostly mammals? Canon 70-300mm f/4-5.6 L IS, also a great travel lens.Ultimate versatility for a strong-armed photographer? Sigma 50-500mm OS, aka the "Bigma". Bears? I'd go for as long a focal length as possible

You can never have enough focal length for small birds. For other wildlife, 300mm ought to be fine.
